An altazimuth mount or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.
Mount Tom State Park is a public recreation area lying south of US Route 202 in the towns of Washington, Litchfield, and Morris, Connecticut. The state park occupies 231 acres (93 ha) on the southwest shore of Mount Tom Pond [ 4 ] and is home to the Mount Tom Tower , which was listed on the National Register of Historic Places in 1993.

William Herschel's 49-inch (1,200 mm) 40-foot telescope on an altazimuth mount. Altazimuth, altitude-azimuth, or alt-az mounts allow telescopes to be moved in altitude (up and down), or azimuth (side to side), as separate motions. This mechanically simple mount was used in early telescope designs and until the second half of the 20th century ...
The equatorial describes the sky as seen from the Solar System, and modern star maps almost exclusively use equatorial coordinates. The equatorial system is the normal coordinate system for most professional and many amateur astronomers having an equatorial mount that follows the movement of the sky during the night. Celestial objects are found ...
The predecessor of Celestron was Valor Electronics, an electronics and military components firm founded in 1955 by Tom Johnson. [1] [2] [3] Johnson became involved with telescopes when he built a 6" reflecting telescope for his two sons. [2] In 1960, Johnson established the "Astro-Optical" division of Valor, which would later become Celestron. [3]
A large German equatorial mount on the Forststernwarte Jena 50cm Cassegrain reflector telescope. An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, called polar axis, parallel to the Earth's axis of rotation. [1] [2] This type of mount is used for astronomical telescopes and cameras.
Mount Tom State Reservation encompasses the Mount Tom Range and is located in the Connecticut River Valley region of Massachusetts, just north of the city of ...
Equatorial platform: The use of equatorial platforms (such as the Poncet Platform) fitted under the altazimuth mount has given users limited equatorial tracking for visual and astrophotographic work. Such platforms can incorporate a clock drive for ease of tracking, and with careful polar alignment sub-arc second precision CCD imaging is ...
